Meghan Markle and Prince Harry stepped out together in London, England, on Tuesday to attend an important cause.

The two were on hand for the 2018 WellChild Awards at the Royal Lancaster Hotel, which celebrates the inspirational qualities of the U.K.'s seriously ill children and young people, along with those who go that extra mile to make a difference to their lives. Harry has been a patron of WellChild since 2007.

During his speech, Harry have his beaming wife a shout-out.

"For the past 40 years, WellChild has been identifying issues and finding long-lasting solutions so that families can care for and support their children at home in the very best possible way," he said. "I have been a patron of the organization for 11 years now, and this year I am especially grateful to be able to share the scope and magnitude of this work with my wife, who joins me here this evening."

Kensington Palace tweeted a sweet throwback picture of Harry attending the annual event more than a decade ago, side-by-side with new pictures of Harry still connecting with the children today.

On Tuesday, Meghan looked chic in all black, sporting trousers and a blazer, and rocking her signature messy bun. Meanwhile, Harry looked dapper as usual in a blue suit.

Kensington Palace tweeted photos of the Duke and Duchess of Sussex meeting children at the event, including 7-year-old Matilda -- who has spina bifida and is paralyzed from the chest down -- and who greeted the royal couple with a big smile.
